As a side note: they could have safely used another '@', as the proxying
protocol allows for stacking the user domains
(e.g. address@hidden@bway.net).

So, your server received the name as "address@hidden" anyway.

If I get it right, the domain_split function should return the part
between '%' and '@', if there is a percent sign, the part after '@',
if there's none, and "bway.net" otherwise. Does that make sense? If
so, the following function will do it:

string
domain_split(string name)
{
         integer a;
         string localpart;
         string domainpart;

         domainpart = "bway.net"; /* provide the default value */
         if (name =~ "\(.*\)@\(.*\)") {
                localpart = \1;
                domainpart = \2;
         } else {
                localpart = name;
         }

         if (localpart =~ "\(.*\)%\(.*\)") 
                domainpart = \2;

         return domainpart;
}

Here's its output in the test run:

** TEST SHELL **
(radiusd) source /home/gray/1.rw
0
(radiusd) r domain_split("username%domain.com")
domain.com
(radiusd) r domain_split("address@hidden")
domain.com
(radiusd) r domain_split("address@hidden")
domain.com
(radiusd) r domain_split("username")
bway.net
(radiusd)

Sure, that would be great.
